[Lymphocyte subpopulations in maintenance hemodialysis patients receiving recombinant human erythropoietin]
1Department of Urology, Nara Medical University, Japan.
The effect of recombinant human erythropoietin (rHuEPO) on the lymphocyte subpopulations of maintenance hemodialysis patients has been studied. Peripheral lymphocyte counts, lymphocyte subpopulations (Two color analysis) and PHA-induced proliferative response were measured before and after rHuEPO administration during 8 months in 22 stable hemodialysis patients (mean age 52 years, mean duration of dialysis 48 months). We could find a significant increase in the proportions of CD4+ Leu8- cells, HLA-DR+ cells, CD8+ HLA-DR+ cells, CD14+ HLA-DR+ cells and CD4+ Leu8-/CD8+ CD11b+ cells ratios after rHuEPO therapy. In addition, a significant decrease in the proportions of CD16+ CD57- cells and CD20+ cells could be found after rHuEPO therapy. These results suggest that rHuEPO administration to stable hemodialysis patients induces increases in lymphocytes categorized into helper subset groups and in activated T lymphocytes.
